(GRANTED UNDER THE ACT GF MARCH 3, 1883, AS AMENDED APRIL 30, 1328; 370G. 757) mit functioning of the delay firing mecha nism.

In designing a fuse which will meet this requirement and which may beeasily constructed and readily assembled I have incorporated therewith anovel form of superquick and mechanical delay firing mechanism elementsof which are insertable as units in the fuse.

With the foregoing and other objects in view, my invention resides inthe novel arrangement and combination of parts and in the details ofconstruction hereinafter described and claimed, it being understood thatchanges in the precise embodiment of the in vention herein disclosed maybe made within the scope ofwhat is claimed without departing from thespirit of the invention.

A practicalembodiment of the invention is illustrated in theaccompanying drawing, wherein:

Fig. 1 is a longitudinal sectional view of the improved fuse shown inthe normal unarmed position;

Fig. 2 is a similar View showing the delay firipg mechanism in positionof operation, anc

Fig. 3 is a sectional view on the line 33 of Fig. 1.

Referring to the drawing by numerals of reference:

In carrying out the invention there is pro vided a container consistingof a hollow head 5 which is in threaded engagement with a body 6 formedwith a cavity 7 in its forward portion. In the floor of the cavity is adisk 8 having a central aperture 9 and also an annular recess 10 in itsforward face for seat- The carrier 1s enlarged ing a carrier 11. as at12 intermediate its'ends and threaded to the forward walls of the body6, an arrangement which lends support to the body to withstanddeformation on ricochet impact.

It is formed with a small bore 18 in which 'are placed nested thimbles14 whose closed and has a stem 22 whose forward end 23 issemicylindrical and this semicylindrical end is provided with a notch 2aadapted to receive a complementary projection 25 on the semicylindricalportion of a dog 26; The dog is pivoted by a pin 27 to a ring 28 adaptedto seat on the forwardface of an apertured disk 29 held in place againstthe carrier by the nose 30 of the fuse. A spring 31, confined betweenthe collar 21 and the disk '29, urges the firing pin towards thedetonator but this action is restrained as long as the dog is heldagainst pivotal movement by the disk 29.

The firing pin is capable of being released from the dog when on impactof the fuse itis moved forwardly by reason of its inertia to theposition shownin Fig. 2. The spring in recovering forces the dog out oflocking engagement and drives the firing pin home. This action willcause a delay firing of an auto-selective character, especially suitablefor obtaining an air burst when the projectile is ricocheted. The firingpin 20, dog 26, collar 27 and disk 29 are assembled as a unitforinsertion in the carrier.

The nose 30 of the fuse is insertable through an opening 32 in the fusehead and is threaded to the carrier. It is formed with a chamber 33conformable to the large bore 18 in the carrier to allow for the forwardmovement of the firing pin unit. .Mounted in the nose and having accessto the chamber 33 is a striker 34 which when driven inwardly comes intocontact with the dog shearing the pivot pin 27 and forcing thefiringypin to set off the detonator and produce a superquick functioningof the fuse. The striker is held in place by a shear pin and is furthermaintained in the safe position by half blocks 36 which are encircled bya weighted tape 37 centrifugally released during'fiight.

A cap 38 is threaded to the nose to retain the half blocks and it isremoved only when the fuse is to be setfor super-quick action.

The body 6 of the fuse is formed with an eccentric cavity 39 in which ispivoted a rotor e0 confined. by the disk 8 and carrying a detonator ll.The rotor is maintained in the un armed position with the detonator outof axial *alinement by means of'a pin l2 which functions on set-back torelease the rotor which is then free to move to the armed position underthe influence of centrifugal force. In the armed position the rotorbears tightly against The wall of the cavity and is thereby re strainedagainst counter movement due to force set up on impact. Because of thedi rect connection between the nose of thefuse and the disk 8 anypressure resulting from impact will act to prevent counter movement ofthe rotor.

I claim 1. In a fuse, a body formed with a cavity, a disk on the floorof the cavity, a hollow head ittached to thebody, a detonator carrierattached intermediate its ends tothe forward end of the body and restingon the disk, a nose insertable through the hollow head and attached tothe carrier, a mechanical delay'fir- Ing mechanism assembled as a unitand held in place by the adjoining ends of the nose and carrier, astriker carried by the nose'in line with the delay firing mechanism,centrifugally releasable means for holding the striker inoperative and acap removably secured' to the nose for holding said meansin place.

2. In a fuse, a body formed with a cavity, a disk on the floor of thecavity, ahollow head attached to the'body, a detonator carrier attachedintermediate its ends to the forward end of the body and resting on thedisk, a nose insertable through the hollow head andattached to thecarrier, a mechanical delay'firing mechanism assembled as'a unit andheldin place by the-adjoining ends of the nose and carrier and -a strikercarried by thenose in line with the delay firing, mechanism.

3. In a fuse, a body, a hollow head attached to the body, a detonatorcarrier attached intermediate its ends to theforward end of the body, anose'insertable through the hollow head and attached to the carrier, amechanical delay firing mechanism assembled as a unit and'held in placeby the adjoining ends of the nose and carrier, and a striker carried bythe nose in line with the delay firing mechanism.

l. In a fuse, a body, a hollow head attached to the body, a detonatorcarrier attached intermediate 5 its-ends to the forward end of the body,a nose insertable through the hollow head and attached to the carrier,the carrier and nose formed to provide a chamber, a delay firingmechanism positioned in said chamber and an impaetstriker in the nosecapable of actuatingth'e delay firing mechanism.

5; In a fuse, a'body, a hollow head attached to the body, a detonatorcarrier attached to the body, a nose insertable through the hollow headand attached to the carrier, the carrier and nose :formed to provide achamber, a delay firing mechanism positioned in said chamber and animpact striker in the nose capable of actuating the delay firingmechanism.

6. In a fuse, a two-part'casin'g, an apertured disk held between theparts of the easing, a firing pin having a collar and a semicylindricalnotched end portion insertable through the aperture in the disk, a doghaving a semi-cylindrical end portion insertable through the aperture inthe disk and engageable with the notched end of the firing pin, a ringin which the dog is pivoted, a spring confined between the collar ofthefiring pin and disk and a striker spacedfromthe dog and engageablewith the dog on impact to break its pivotal connection on the ring.
